Yes, if we add a lot of H₂, the value of K will start falling, which will cause the reaction to move forward. The minimum pressure of H₂ needed to reverse it is 3.598atm.

The force applied per area is referred to as pressure.

ΔG° = -RT ln(K)

34000 = 8.314(273 + 1126)ln(K)

ln(K) = 2.9231

K = [tex]e^{2.9231}[/tex] = 18.834

Since the container doesn't contain any H₂ gas, K will therefore start out at infinity. The reaction will move in the opposite direction in order to reach equilibrium. Consequently, the pressure of N₂ will initially rise.

2 ounces of water will be measured using the measuring cup introducing before part A when making the cake.

Both units (that is, ml and ounces) are equal, meaning they measure the same quantity and can be converted to each other.

Given that:

1fluid oz = 29.7ml

Part A measurements are not shown. Therefore, we will explain using hypothetical values.

Let the amount of water measured with the measuring cup in part A be 10 ml.

The equivalent number of ounces (x) is calculated as follows:

1 fluid oz = 29.7ml

x = 10ml

By using equality

x * 29.7ml = 1 fluid oz * 10ml

By canceling common units

x * 29.7 = 10 fluid oz

Divide both sides by 29.7.

x = 0.3367 fluid oz

Approximate to the nearest half.

x = 0.5 fluid oz

This means that the equivalent amount of water is 0.5 ounces.

What if the measurement is 55mL.

We apply the same steps here also:

x fluid oz = 55ml

x *29.7 = 1 fluid oz * 55 ml

Divide both sides by 29.7

x = 2 fluid oz

This means that the equivalent amount of water is 2 ounces.

The molarity of NaCl in enough water is 0.582[tex]\frac{mol}{mL}[/tex]

The moles of NaCl is given which is 0.23 and NaCl is dissolved in enough water which makes the solution of 395.6 mL.

The total number of moles of solute present in a given solution per litre is known as its molarity. In contrast to mass, which varies as the system's physical circumstances vary, the volume of a solution changes as a function of changes in the system's physical qualities, such as pressure and temperature. This has an impact on the molality of the solution. The symbol M, sometimes known as a molar, denotes molarity. A solution is considered to be one molar when one gram of the solute dissolves in one litre of the solution.

So, the molarity= [tex]\frac{totalnumber of moles}{total volume }[/tex]

molarity=[tex]\frac{0.23}{0.395}[/tex]

molarity=0.582[tex]\frac{mol}{mL}[/tex]

Answer:

Hey there! The nuclear symbol for an ion with a charge of +220 protons and 24 neutrons would be written as follows:

220+ 24

The symbol consists of two parts: the atomic number (220+) and the atomic mass (24). The atomic number is the number of protons in the nucleus of an atom, and it is represented by a superscript on the left side of the symbol. The atomic mass is the total number of protons and neutrons in the nucleus, and it is represented by a subscript on the right side of the symbol.

In this case, the atomic number of the ion is 220, which indicates that it has 220 protons in its nucleus. The atomic mass is 24, which indicates that it has a total of 220 protons + 24 neutrons = 244 particles in its nucleus.

________________________________________________________

Nuclear symbols are a way of writing down the important information about atoms and ions in a short and easy-to-read format. They usually consist of two parts: the atomic number and the atomic mass. The atomic number tells us how many protons an atom has in its nucleus, and the atomic mass tells us the total number of protons and neutrons. For example, the nuclear symbol for carbon is 6 12C, which tells us that carbon has 6 protons and 12 particles (6 protons + 6 neutrons) in its nucleus.

To determine the number of protons in an atom or ion, we can look at its atomic number, which is usually written as a superscript on the left side of the nuclear symbol. For example, if the nuclear symbol for an atom or ion is written as 6 12C, we can tell that it has 6 protons. To determine the number of neutrons, we can subtract the atomic number from the atomic mass. For example, if the atomic mass is 12 and the atomic number is 6, then the number of neutrons is 12 - 6 = 6. To determine the number of electrons, we can just look at the overall charge of the atom or ion. If it is neutral, then it will have the same number of protons and electrons. If it is positive or negative, then it will have more or fewer electrons than protons, respectively.

(A) Vol. of solvent is 119.8 ml, (B) Molarity (M) of sol. is 5.00 M, (C) V1 of copper nitrate solution is 187.5 ml, (D) The instruction given is false.  

(A). To calculate the volume (ml) of a 2.25 M potassium hydroxide solution that contains 15.0 g of solute, we can use the formula:

The unit of measurement for molarity (M) is moles of solute per liter of solvent.

Rearranging the formula to solve for liters of solvent:

Molecularity = moles of solute / liters of solvent (M)

We know that the molar mass of potassium hydroxide (KOH) is 56.1 g/mol. To find the moles of solute, we can divide the given mass (15.0 g) by the molar mass of KOH:

15.0 g / 56.1 g/mol = 0.2679 moles

Now we can plug this value into the formula above:

Liters of solvent = 0.2679 moles / 2.25 M

Liters of solvent = 0.1198 L or 119.8 ml (rounded to 3 significant figures)

(B). To calculate the molarity of a solution containing 1.25 moles of glucose in 250. ml of solvent, we can use the formula:

The unit of measurement for molarity (M) is moles of solute per liter of solvent.

Plugging in the given values:

Molarity (M) = 1.25 moles / 0.250 L

Molarity (M) = 5.00 M

(C). To calculate the volume of a 10.00 M copper(II) nitrate solution that must be added to water to prepare 750.0 ml of a 2.500 M solution, we can use the formula:

M1V1 = M2V2

Where M1 and V1 are the concentration and volume of the original solution, and M2 and V2 are the concentration and volume of the final solution.

We know that the final solution has a volume of 750.0 ml and a concentration of 2.500 M, so we can plug in these values for V2 and M2:

M1V1 = 2.500 M x 750.0 ml

Now we can solve for V1 (the original volume) by rearranging the formula:

V1 = M2V2 / M1

V1 = (2.500 M x 750.0 ml) / 10.00 M

V1 = 187.5 ml (rounded to 4 significant figures)

(D). The instructions "Take 100.0 mL of the 10.0 M solution and add 900.0 mL water" are not correct for diluting a 10.0 M solution to a 1.00 M solution.

To achieve this dilution, you would need to take a smaller volume of the 10.0 M solution and add a larger volume of water, because the final volume should be larger than the starting volume.

For example, you could take 10.0 mL of the 10.0 M solution and add 90.0 mL of water, which would give you a final volume of 100.0 mL and a concentration of 1.00 M. The instruction given above is false.

When only 1 mol of oxygen was intended to be produced, a process instead yields 4.93 L of oxygen. The percent yield of the reaction is 493%.

Percent yield is a measure of how much of the desired product is produced in a chemical reaction. It is calculated by comparing the actual yield of a product to the theoretical yield, which is the amount of product that would be produced if the reaction were 100% efficient.

To calculate the percent yield, you can use the formula:

= percent yield

= (actual yield / theoretical yield) x 100%

The theoretical yield of a reaction is calculated by multiplying the number of moles of reactant used by the stoichiometry of the reaction. In this case, the reaction is supposed to produce 1 mol of oxygen, which is the theoretical yield. To calculate the actual yield, we can use the Ideal gas law PV = nRT, where P is the pressure, V is the volume, n is the number of mol. Since we know that V = 4.93 L, we can use this information to find n:

= n

= (PV) / RT

The actual yield is 4.93 L of O2 or 4.93 L of any gas at STP (Standard Temperature and Pressure) is equivalent to 4.93 moles of O2.

Then we can use this information to calculate the percent yield:

= percent yield

= (actual yield / theoretical yield) x 100%

= (4.93 moles O2 / 1 mole O2) x 100%

= 493%

So, the percent yield of the reaction is 493%.

It's important to note that a percent yield of greater than 100% is usually an indication of an error in the measurement or calculation of the actual yield, or it could be an indication that the theoretical yield is incorrect.
